Filed: 1937-06-23
Abstract: 490,791. Cigarette-making machines; adhesives. AMERICAN MACHINE & FOUNDRY CO. June 23, 1937, No. 17450. Convention date, April 6. [Class 130] In a machine for applying sections of tipping material to a travelling cigarette wrapper web, a coating of thermoplastic adhesive is applied to the tipping material during feeding at such a point that the adhesive will harden before reaching the wrapper web. The thermoplastic adhesive is colourless, odourless and/or transparent and may comprise a mixture of Carnaubawax and Damargum, or a solution of thermoplastic material in asolvent, e.g. a solution of gums and/or resins and pyroxylin in a solvent such as an ether of ethylene glycol. The adhesive is supplied by a roller 11 from a heated receptacle 18 to a web C of tipping material and allowed to harden before the web C is fed between spring-pressed rollers 14, 15 and through a guide 24 to the space between a rotating drum 25 and a bracket 28 where sections are severed by a knife 26 which co-operates with a ledger member 27. The sections are simultaneously heated and pressed against the web P of wrapper material by a segment 34 on a roller 33 which rotates about a stationary hollow support enclosing an electric heater.

Abstract: 829,591. Extruding predetermined volumes of margarine &c. UNILEVER Ltd. June 3, 1957 [June 8, 1956], No. 17550/57. Class 87(2). [Also in Group XXVIII] A cylindrical member la with a diametrical channel lc rotates in a casing I which has an inlet 2 and an outlet 3, diametrically opposed, and a piston lb reciprocates in the channel and allows margarine to enter the channel while it ejects a previously measured quantity, the rotational velocity of the member 1a being a minimum when the channel 1c is aligned with the openings 2, 3. The drive is taken from a constantly rotating shaft 17 which, through worms and worm-wheels, rotates axles 12, 31 and 11. A cam 18 on the axle 12 oscillates a lever 19 and thereby, through a link 21, oscillates a lever 23 about a journal 22 and this lever 23 reciprocates piston lb as disclosed in Specification 710,277. A slotted arm 38, Fig. 4, is keyed to the axle 31 and a gear-wheel 33 is rotatable on a cylinder 34 which is eccentric to the axle 31 and projects from the frame. A roller 41, carried by the gearwheel 33 near its periphery, engages the slot 39 in the arm 38. Owing to the eccentricity, constant rotational velocity of the arm 38 results in variable rotational velocity of the gear-wheel 33, this being a maximum at the position shown in Fig. 4. The gear train from the gear-wheel 33 provides a gear reduction of 2 : 1 so that the minimum rotational velocity of the member 1a occurs twice every revolution. A cam 7, rotated from the axle 11, oscillates through linkage a bar 4 which actuates a convential cutting mechanism (not shown) twice during each revolution of the member la when the channel 1c is not in communication with the outlet 3.

Title: Improved method of coating articles of all kinds with thin layers of metals or metalloids
IPC: H01L21/18
Filed: 1930-06-06
Abstract: In coating articles in a vacuum with metals or metalloids by thermal vaporization of the coating material the metal or metalloid is deposited as a coating on an electrically conductive carrier material of high melting point which does not alloy or combine with the metal or metalloid.  For example, tantalum wire may be coated electrolytically with silver which is then vaporized and deposited on the article to be coated by passing an electric current through the tantalum wire in a vacuum.  For coating with cadmium, the cadmium may be applied to a cobalt carrier by drawing a cobalt wire through molten cadmium.  The carrier may comprise a protective layer, which will not alloy or combine with the substance to be vaporized, applied to a substance with which the substance to be vaporized would alloy or combine, e.g. for coating with gold tantalum wire is coated with a layer of tantalum carbide and gold is then applied electrolytically. In another example tantalum wire is coated with tantalum carbide and silicon is then deposited thereon by heating in an atmosphere of silicon hydride, the silicon being then vaporized on to the article to be coated by heating the tantalum wire electrically in a vacuum.

A well-tool receiving and locating unit is incorporated in parallel tube strings which serve both as hole casing and tubing for production from different horizons, and comprises two sets of top and bottom coupling connections for joining to the two strings, two fully open bores for alignment with the strings, and ports in the walls of the bores whereby the bores may be brought into or closed off from communication with one another in establishing various flow paths as controlled by selective disposition within the unit of different retrievable tools. The unit is installed just above the uppermost producing zone, and consists of fully open bore members 1, 2 welded together at 3 and communicating with one another through ports 13, 24 and an off-set chamber 23. Fig. 4 appears to be distorted, being a section on line 4-4 of Fig. 5. The member 1 is coupled at 6 to the string 7, and the member 2 is provided with top and bottom couplings for connection to a parallel to the string 7, and is widened to form a space 20 which communicates with and provides access for the positioning of tools in or retrieving tools from the chamber 23. The member 1 is formed with a tool-locating seat 10, a groove 11 for receiving the latch dogs 43, and a groove 12 in line with the port 13, the surfaces above and below the groove 12 being machined smooth to mate with the sealing rings 48, 49 of the tool. The member 2 and chamber 23 have similar locating seats 30, 27 and latch-dog grooves 31, 28, and machined sealing surfaces 29, 32, 34 are provided. The bores 1, 2 and chamber 23 can receive various flow blocking and flow directing plugs in preselected relationship for any of different working and reworking operations. For example, when the well bore is not to be lined with casing, the space outside the strings may be cemented and thereafter conventional wire line operations, e.g., perforating at each production zone, can be effected through the production strings. Fig. 4 shows tools 40, 41, 36 seated in the chamber 23, members 1, 2 respectively for an operation involving, for example, cement squeezing steps wherein a preparatory circulation of washing liquid is followed by the introduction of the cement slurry with pressure liquid behind the slurry.

The flow down through the tool 41 is checked at 49 and passes through ports 13, 24 and passage 23, which is plugged at the top at 45, to the outside of an extension tube 35 of the desired length, and returns up through the pipe 35 and tool 36 to the parallel production string.
Patent GB-613267-A (GB)
Title: Improvements relating to the shrinkproofing of materials consisting wholly or partlyof wool
IPC: D06M15/643
Filed: 1946-06-14
Abstract: The shrinkage tendency of materials consisting partly or wholly of wool is reduced by the formation on the surface of the materials (which contain initially 10-30 per cent moisture) of an adherent solid polymeric deposit in amount between 1.5 and 4.0 per cent of the material, which deposit is produced by hydrolysis in water or dilute alkali of a silane of the type <FORM:0613267/IV (c)/1> when R is alkyl or aryl and X1, X2 and X3 bromine or chlorine, the material after treatment being washed. A mixture of a silane as above with one of general formula <FORM:0613267/IV (c)/2> may also be used, X1, X2, R1 and R2 having the same significance as above.  The silane or silane mixture may be applied in solution or as a vapour, preferably at a temperature above 50 DEG  C.  After immersion in water the material is dried, the hydrolysis taking place during the drying. The firmly adhering deposit is resistant to scouring and to dry-cleaning agents.  5 per cent or more of it produces a rough fabric with abrasive properties, and in consequence reduced wear resistance.  The feel of the fabric may be improved by treatment with a soap, cation-active compound or other softening agent.  Long chain alkyl silanes give a soft handle when used in the extent of 20 per cent in a mixture, but used alone they do not give a good measure of unshrinkability.  The wool may be dyed or dyed wool may be treated, but in the latter case the shade may be altered.  In an example 100 g. of wool with a moisture content in equilibrium with the atmosphere is boiled for 20 minutes in 0.5 per cent by volume of methyl trichloro silane in carbon tetrachloride.  After immersion in water for 10 minutes it is dried in a current of warm air, and washed in a soap solution.  Area shrinkage of the fabric is reduced from 25 per cent to 4 per cent.  Specification 594,901 is referred to in the Provisional Specification.

[Also in Division H3] An oscillator comprises an active element having a tunable frequency determining circuit connected to its output electrode and an oscillation producing feedback capacitance connected between the output electrode and the input electrode, further regenerative feedback being provided by inductive coupling between the electrodes so as to increase the feedback at lower frequencies. Fig. 1 shows an oscillator for an H.F. tuner and comprising a transistor with a grounded base and with the resonant lines tuning collector and emitter circuits regeneratively coupled through a capacitor 12 to cause oscillation. The coupling loop 13 for the emitter circuit is extended at 17 into the collector circuit so as to provide additional regenerative feedback at the lower end of the tuning range to maintain the output of the oscillator more nearly constant. The feedback loop together with the inductance preferably resonates below the lowest operating frequency. In an alternative self-oscillating frequency changer circuit (Fig. 2, not shown) the inductive coupling is effected by mounting the rotor plates of the tuning capacitors on a common shaft and connecting this to earth through a small inductor. The resonant circuits for the tuner unit of the frequency changer may comprise two lines (Fig. 3) tuned by capacitors 21 having the moving elements mounted on a common conductive shaft 22 earthed at its extremities but connected to the centre partition through spiral fingers 25 which have sufficient inductance to couple the two lines together. The fingers may be formed as a comb and as the value of the inductance depends upon the effective width of the comb it may be varied, to vary the coupling, by bending back a desired number of the teeth.
